Dog Lights for Night Walking, 2 Pack 4 RGB Modes Dog Collar Light, Rechargeable Dog Walking Light for Nighttime Clip On, IP68 Waterproof Safety Light for Running, Cycling, Camping (Black)

They work great; they hold their charge. It's a pretty good, bright light at night, and I actually live out in the woods, so it's a plus that I can actually see it on the dog at night. It's easy to charge and easy to change from collar to collar, and it's been very dependable. I've had this for several months now.

These collar lights are bright and ideal for the pitch black nights and mornings. The idea that it’s a two pack is great because you can have one fully charged to switch at all times.

Very bright and easy hook up and removal. I hook one onto my German shepherd puppy’s chest ring on his vest. Two pack is great and the price is right. I’d buy them again

These work very well. They stay charged a long time. They are fairly bright. Down side... the plastic clasp breaks off after a month or so of walking the pup (Catahoula). Wish these were more durable. Gone through several packages. Luckily not too expensive.

These lights are extremely bright, have different flashing patterns, and a very white steady option as well. In my own yard, when I let the dog out, I can find him wherever he goes. When walking, the light alerts drivers. Very safe.
